Eight-bay desktop NAS for teams
The TS-855X-8G-US is an eight-bay desktop NAS powered by an Intel Atom C5125 eight-core processor at 2.8GHz and 8GB of DDR4 memory. It targets small teams that need centralised file sharing, backup for Google Workspace and Microsoft 365, and light virtualisation. Dual PCIe Gen 3 x4 slots allow extra network or fibre-channel cards, while dual M.2 slots accept NVMe drives for cache or storage pools.
Thermals and power in daily use
The unit uses its standard chassis fans to cool the 2.8GHz processor and the installed drives during typical file-server workloads. Acoustic output stays at a background level suitable for an office desk, and power draw scales with the number of spinning 3.5-inch and 2.5-inch drives rather than spiking under normal multi-user access.
Build quality and daily connectivity
The steel enclosure holds six 3.5-inch SATA bays and two 2.5-inch SATA bays behind a lockable front panel. A single 10Gbase-T port and two 2.5GbE ports provide high-speed wired links without extra cards. The two PCIe slots and two M.2 slots are accessible by removing the side cover, so adding cache drives or a QM2 card does not require moving the NAS in the rack or on the shelf.

Perguntas sobre este artigo
How do I install drives in the six 3.5-inch SATA bays and two 2.5-inch SATA bays, and what step do people miss?
Insert 3.5-inch HDDs into the six front trays and 2.5-inch SSDs into the two internal bays, then lock each tray; the step often missed is seating the SATA connector fully before closing the latch.
What maintenance or replacement will the 8GB U-DIMM DDR4 memory need later?
The 8GB U-DIMM DDR4 can be expanded up to 128GB with ECC support; plan to add matching modules if workloads grow beyond the factory capacity.
What limit appears first when the Intel Atom C5125 8C 2.8GHz processor runs sustained workloads?
The 8-core 2.8GHz CPU will hit its thermal and compute ceiling before the 10Gbase-T or dual 2.5GbE network links saturate during heavy virtualization or encryption tasks.
